Noel, the 419 has two "input modes" for selecting bands using the connector on the rear:
PBM = Per Band Mode, where 12V is put on an appropriate pin for the band you wish to select, that is, one of 6 pins. BDM= Band Data Mode, where Band0 to Band3 data is applied to the connector, and the 419 does the decoding. The pin outs for the connector for either mode are etched on the back of the 419. To enter BDM, hold the mode button and push and release the 10m button. If you look under the 10m button, you'll see a label "BDM". To enter PBM, hold the mode button and push and release the 15m button. If you look under the 15m button, you'll see a label "PBM". 73, Vic VE3YT -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-with-the-AS-419-bandpass-filter-system-tp7627818p7627840.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
